Patented Jan. 19, 1954 UNITED STATES it TENT OFFICE ADHESIVE METAL FOIL, BOTTLE CAP THEREOF, AND METHOD This invention relates to metal foil, one side of which is coated with adhesive material, articles made therefrom, and methods of manufacture.

The principal object of my invention, generally considered, is to produce metal sheet or foil material which is suitable for application to objects, an example being corked necks of bottles, using heat or moisture, articles made from such material, and methods of manufacture.

Another object of my invention is the production of adhesive foil material in which an intermediate layer of heat-softening cement serves as f a binder between a nlm coating of remoistening glue and the metal foil.

A further object of my inve-ntion is the provision of metal foil so treated that it may be sealed to itself or applied to any surface by the alternative means of heat and moisture,

A still further object of my invention is to provide a sheet of metal foil having adhesive on one side, this adhesive being applied directly to the metal without the use of an intermediate layer of paper, a transparent primer being used instead which permits' the metal to show through on the gummed. side, which can be attractively colored if desired, and when a label produced from this material is applied to a transparent bottle the metal on the gummed side will.l show through the bottle which is to be desired as it shows that the label is entirely or" metal.

Another object of my invention is to produce oil, one side of which is first coated With a lilm of heat-softening cement and said hlm is, in turn,

coated with a film of remoistening glue, the difneck and sealed thereto, either by heat or after moistening, by crimping in place therearound, providing a tamper-proof closure.

A further object of my invention is to provide a metal hood which can be sealed over the top of a corked or capped bottle, as by using heatsoftening and/or reznoistening adhesive between the hood and bottle, and/o1` crimping said hood on the bottle neck said hood having perforations therearound slightly below the parting line of the cork or cap from the bottle, and said perforations terminating at a tab properly marked and indented at the beginning of the perforations, so that in lifting and pulling the tab, the metal hood will start tearing at the perforated line and tear cleanly around the bottle, leaving the pouring lip clear and free from possible contamination from the hood.

A still further object of my invention is to provide a tamper-proof closure which is made of thin metal provided with suitable means of attachment to the neck of a bottle and with means for opening which destroys the closure when opened, thereby avoiding the objection to other closures currently used for this purpose which are made from some form of cellulose, may readily be removed by soaking in water, and can be replaced after removal and will again dry to original form without injury to the closure, and still others in current use of paper-backed foil having alayer of remoistening gum applied to the paper back, which paper back provides a wick action on the liquid being poured from the bottle, retaining this liquid, andmaking the pouring lip of the botle Wet, unsightly and unsanitary.

An additional object of my invention is to provide an attractive decorated hood for the neck of a bottle which may, if desired, entirely enclose the top of the cork or have the top of the cork exposed to permit the decorated top of the cork to appear and allow the government tax stamp to be affixed directly thereto.

A further objectof my invention is to provide a hood closure applied to a bottle neck in such a manner that the lower portion only, below a perforated strip, is iirmly fastened to the bottle, leaving an upper or removable portion free from adhesion to the bottle sovthat it can be readily removed therefrom, accomplished as by only moistening the bottle below the perforation line or, if the closure applied by means of heat, only applying the heat below the perforation line. Y

Other objects and advantages of the invention, relating tothe particular arrangement and come bination of the various parts, will become apparent as the description proceeds.

Referring to the drawing,

Fig. 1 is an elevational View of a blank from which bottle caps embodying my invention may be produced.

Fig, 2 is a sectional View on the line II--II of Fig.v l, in the direction of the arrows.

v Fig. 3 is an elevational view of a bottle cap such as may be produced from a blank such as illus- Referring to the drawing infdetaiL, like parts.y being designated by like reference charactersand iirst considering the embodiment of my invention illustrated in Figs. l and 2, there is shown a sheet of metal foil 9, to oneside` of-.which is applied a film or coating of heat-softening cement S. Such cement is desirably formed -ofa suitable vinyl resin or polyvinyl butyral, applied either in solutionV or in molten state; or a cement composed of phthalic anhydride and ethylene glycol, or other resin type adhesive, and during application is preferably. of such a consistency that it may bewapplied by a roller in a continuous process; Such a process isV disclosed in theV Nadeau Patent. No. 2,322,048, dated June 15, 1943.

In other words, referring vto Fig. l of the drawing oi said patent, asheet of metalV foil 9 of desired width and thickness, such for example .002 inch in thickness, may be passed from a supply roll into Contact withan applicator roller, which carries up and into contact with thel undersurface o the sheet an appropriate amount or"v the heatsoftening cement` contained in a hopper in which the roll rotates; The cement in theV hopper is maintained fluid by keeping at a suitable temperature or may be applied'in solution,` the solvent later driven oil", as in an overr.

After application of a. nlm 8 of' such cement to the undersurface of the foil, saidfilm is'cocled or dried, such as naturally in the air orv in a cooler, if applied hot, or itV asa solution preferably oy passing through a drier, such as that indicated by the reference character 5 in the patent referred to. After cooling or drying, so that the cement hassolidiied or hardened, the surface of the lm 8 is, in turn, coated with a film 'l of reinoistening glue. This may be accomplished in any desired manner, as by passing into contact with an applicator roller. similar to the applicator'roller'used for applying the heat-softening cement, which roller deposits thereon a film of remoistening glue, which may be a good dextrin glue, or which may be combined with animal glue, and which obviously should be compatible with the heat-softening cement.

The applicator roller revolves in a hopper containing such glue of the proper. consistency, so that after. the application of the film, it is readily dried, either naturally in the air, or preferably by passing through a drier such as indicated in the patent referred to by the reference character 9. After emerging from the drier, if used, the foil passv through guide rolls such as those represented' by the reference characters 12 and 13 in the patent referred to. The doubly coatedv foil may then be linally wound up on a drive roll, such as that designated by the refer ence character l0 in said patent.

From the foregoing, it will be seen that I iirst produce a, preferably quite thin, sheet or teil of metal, which .may be.v aluminum., copper, -bln or any metal, preferably non-rusting, as desired. The uncoated side of the foil may be colored and/or decorated as indicated at ii in Fig. 1 and cut to size, an example being represented in the same figure. In this example, there is shown how to make a blank for a bottle cap, but it is obvious that I do not wish to be limited to this use, as my foil may serve for making any article which it isv desired to supply to some other object. It is, however, particularly adapted for making tamperprooi closures such as the bottle caps represented in Figs. 3 to 6 inclusive.

In the` specic embodiment I have shown a bottlefcapv blank l which is generally sectorshaped, and along the small circumferential edge isa series` oiperforations 6, providing a readily separable circumferential edge strip terminating at one end in a tab d bearing the legend Pullv Here and an arrow directed as in Fig. l, Fig. 3, or Fig. e, for a purpose which will subsequently be'v explained. The perforation line may beplaced at any location, thus permitting theunsealing of thevcap at point desired.

Fig. 3 shows one embodiment of my bottle cap Irl' in1whicha blank, such ask designated I in Fig. 1', is wrapped around a truste-conical mandrel of a size corresponding with a bottle neck to which the produced cap is to be applied, as in Fig. 6, and whereby overlapping radial' edges of the blank are subsequently sealed, preferably by heat, along the radial band betweenv the lines I2 and Il, but either by the application of heat or the moistening of the glue in that area.

The mandrel is also of such a size that the small end of the cap produced projects beyond the end thereof, whereby upon the application of pressure to said end, an inturned annular flat flange, such as represented by the reference character 24 in Fig.` fr, 2S in Fig. 5, and25 in Fig. 6, is formed in a plane transverse to the axis or" the mandrel. A fragmentary portion of the material from which such a iia-nge is formed is also shown in Fig. 1, where it is designated 23. This ange, when the cap is in place, will extend overfthe top'of the'cork and yet not entirely cover the cork. It is not desirable to entirely cover the cork because, in most cases, the cork is decorated and there is a government strip stamp which is applied. It is desirable that this stamp be applied directly to the cork. In cases where it is desirable to entirely enclose the top of the cork, a round metallic disc can be applied over the cork, and the cap applied over said disc, making a completely metallic enclosure. Such a disc may be applied to the top of the cork prior to the applying of the hood, placed inside the hoody prior to application, or permanently incorporated with the hood by means of heat or moisture at the time the hood is formed. so that the closed end hood can be applied to the neck of the bottle as a unit. Such a disc is marked 30.'

Such a cap I I, as represented in Fig. 3, is-then place'd'over the neck I 9 of a bottle as represented in Fig. 5, corked as indicated by I3. In this embodiment, the foil, heat-softening cement, and glue are respectively designated by the characters 20, 21 and 22. Said cap, of course, fits such a corked neck with clearance, and the completed seal represented in Fig. 5, is produced by the application of resilient pressure to the external surface `of the cap afterI application, so as to crimp the material around the neck and bead, if any, and into. iirm engagementwiththe entire externalsurface. of.. the. enclosed. neck portion. This Aas at the part to engage the cap below the line of perforations, and the cap applied thereover and crimped in place by the use of the remoistening glue coating or film 22 in direct engagement with said neck.

When it is desired to remove a cork from a bottle sealed with one of my caps, after application as shown in Fig. 5, all that is necessary is to grasp the tab labelled Pull Here and unwind the strip 4 from the top of the bottle cap, along the line of perforations 6, I3 or I f3, as the case may be. This operation exposes the cork I8 and makes it possible to then immediately uncork the bottle without any interference from the metal foil or sheet covering, leaving the pouring lip free from contact with the closure.

Fig. 4 illustrates a cap i5 similar to Fig 3, but with a wider pull strip, here designated I t. Such a form would be used where it is desired to remove a larger portion of the cap, as where the cork projected a greater distance from the bottle neck than shown in Fig. 5, or where a screw cap longer than the projecting portion of the cork I8 was employed. Except for this diierence, the form of Fig. 4 is similar to that of Figs. 3 and 5.

Fig. 6 shows how a longitudinal edge portion of a blank overlaps the adjacent edge portion, as indicated at 26, to provide a sealing band. as be- `tween the lines I2 and I 'I of the cap Il illustrated in Fig. 3 The foil, heat-softening cement, and glue, are here respectively designated by the characters 21. 28 and 29.

Fig. 7 merely shows one form of the trademark IU which may be employed, another form being shown in Figs. 1 and 3.

From the foregoing it will be seen that I have produced a material which is an improvement over the conventional paper-back foil, in that there is no paper to assert a wick action on the contents of the bottle when openedand the coated foil can be applied to almost any surface, and when applied, cannot be removed without destroying it. This feature is particularly advantageous in sealing liquor bottles and other vessels requiring tamper-prooi closures.

The treated foil of my invention is cheaper than paper-back foil because the intermediate layer, forming a bond between the foil and the remoistening glue, is cheaper than the paper plus the cost of applying the paper. It is particularly desirable to use my invention for the purpose of f eifecting a hermetic seal around the cork to prevent the latter from drying out, shrinkingand leaking.

Another very important feature is the tear tab and its connected strip. The tab designated 3 or I5, and marked Pull Here, and the notch designated 2, aligns the beginning of the perforations following around the closure along the line 6 in Fig. 1, and 13 and 14, respectively, in Figs. 3 and 4.

This permits an effective uniform method of opening the package by entirely removing the upper portion of the seal, permitting the cork to be withdrawn. The perforated line is customarily placed a short distance below the position of the parting line of the cork with the bottle when the cap is in place, leaving the pouring edge of the bottle clean and clear of any contamination from the cap and cap adhesive. This closure will tear clean and follow the perforations accurately.

Absence of wick action ensures a clean pouring lip.

Although preferred embodiments of my invention have been disclosed, it will be understood that modifications may be made within the spirit and scope of the appended claims, that vthe term cork includes the other means employed for closing bottles, and that the foil, although preferably of metal, may be made of other iiexible material, such as fiber, cloth, paper, and plastic material.
